FLEXIBLE CLOSURE.

Application filed February 18, 19525.

The present invention relates to improve ments in the cam slider tor flexible closure ot the type shown in application Serial l lo. 72 2,3553, tiled July th. lllQ -l, the present 11nprovcnien s being directed to locking means for seeinring; the slider in the desired posltion upon the flexible stringer -i and to the reversible pull nieniber by which the lockino; rneans are controlled and the slider conveniently manipulated in either direction upon the stringers.

in order that the invention may be tully tood itwill first be described with "crence to the accon'inanying drawings and at'ti-n'wards pointed out more particularly 1n the annexed claims.

in said drawings: I

Fig. 9 is a transverse sectional view taken on the line 9-9 of Fig. 1 and showing only the tore-plate of the slider and parts carried thereby Fig. 10 is a detail underneath view of the reversible pull member detached from the slider.

In the type of flexible closure to which the present invention relates, two flexible strips or stringers 1, 2 are formed at their inner edges with beads or thickened portions 3 upon which are secured interlockingfasteninn devices.

Each interlocking;- tastening device is preferably i'ornired with a U-shaped yoke 10 enibracinp; and compressed upon the beaded or thickened edge 3 of a. flexible stringer, a narro'ivneck 12. a forked hook 123, and the opposite riding lugs or shoulders 15. The specific term and operation of the fastening; devices of the preferred construction will be Serial No. 10,062.

more fully understood by reference to the above named application, Serial No. 724,355.

The operating 3H1 slider is preferably constructed set forth in above named application of a back-plate and a fore-plate 21 mounted in spaced relation upon a binder post 22, with a fastener receiving channel between them. The inner faces of the backplate and foreplate are provided with controlling grooves 25 separated by a central guide rib 26. The riding lugs 15 of the :t'a toning devices operate in the controlling grooves The tore-plate .21 iscforined in its outer face with a longitudinal recess 36 in which rests a spring;- blade 31 secured at its upper end by a rivet 32 seated in the bottom of the recess Ill). The lower end of the spring blade 2,1 is formed with an inwardly presentcd angular detent which is adapted to be presented over the lower open ends of controlling grooves 25 of fore-plate 21 to thereby intersect the path or the outer riding lugs 15 of the. fastening devices. The outward set ot the spring blade 81 constituting the supporting arm of the locking detent is such that when unrestrained the detent 35 will be raised above the controlling grooves oi. the slider foreplate as shown in Figs. 5, (3 and 8 of the drawings.

The tore-plate 21is also formed with a guideway 41:0 above and Wider than the reccss 30. This guideway is :toirined by the overhai'lging longitudinal walls 41 either integral with or otherwise attached to the tore-plate 21. The lock controlling pull member is mounted in the guideway l0 and consists ol. a blade 4-5 Ol spring Inetal having rolled or turned over linger pieces 46 and M at its opposite ends. On each side of the pull member adjacent to the finger pieces 4:6 and 1:7 are lateral slots 48 and 49 to receive the inwardly presented guide walls ll above referred to. These guide walls ll are presented in parallel relation and, thrmighout the greater part of their length. they are spaced to correspond with the spacing between the cuts or notches of member 45. At the lower end of the slider these side walls 41 are, however formed with inwardly extending projections 41 to produce a narrow throat through which the web between cuts 48. 48 ot incinber 45 cannot pass. 'lhese portions 4-1 of lllll Q r 1 reassess tracks 41 thereby constitute a stop for limiting the movement of pull member downwardly upon the slider. This pull member 4-5 is also designed to project upwardly from the slider and to limit the movement in the upward direction, member 45 is provided with a stud 45 projecting inwardly near its lower end, which comes in contact with the upper closed end or wall 80 of recess 30 when the pull member 45 is pulled to its upward limit upon the slider.

As shown especially in Figs. 5 and 6 of the drawings, the pull member 4-5 has a spring tendency to assume a slight upward bend, so that whenpressed into its normal position as represented in Figs. 1 and l, both ends of member 45 will be confined beneath the flanges 4:1 and cause the stud 45 topress upon the spring arm 31 and force the detent 35 into its looking position. In this position it will be understood that thedetent 35 will I to open the flexible-closure, the pull member the slider as shown in Figs. 0

which position the locking detent 35 1s also released from itsloclnng position, so that 45 is moved from the position shown in Figs. 1 and 4 into the position shown in Figs. 2 and '5 with the result that the locking detent 35 will be released and will spring outwardlyintounlocked position, and thereby permit the slider to be moved downwardly upon the-stringers by the pull of mem- "ber 4L5;v

' When it is desired to close the closure the v-member 45 is shifted into itsposition above and 6, in

the slider is free to respond to the upward pull member45.
